An Operating System (OS) is system software that manages hardware and software resources on a computer. It serves as an intermediary between users and the computer hardware. The OS is responsible for managing system resources such as the CPU, memory, storage devices, and input/output devices, providing services like task scheduling, memory management, file handling, security, and system execution. It enables the user to interact with the computer through interfaces and allows software applications to run.

An OS ensures that hardware components work in coordination, optimizing system performance and ensuring fairness and resource allocation across processes. It supports multitasking, handles errors, and offers user interfaces such as command-line or graphical user interfaces (GUI).

MODULE	TOPIC COVERED
Introduction to Operating Systems	Overview of OS functions, types, and components. Understanding the role of the OS in managing hardware and software.
Process Management	Process creation, scheduling, termination, and management. Process states, PCB (Process Control Block).
CPU Scheduling	Scheduling algorithms (First Come First Serve, Shortest Job Next, Round Robin, etc.), and their advantages.
Memory Management	Memory allocation strategies: contiguous, paging, segmentation. Virtual memory and page replacement algorithms.
File Systems	File organization, storage, access methods, file types, file permissions, directory structures.
Input/Output Systems	I/O hardware, buffering, device management, and techniques for optimizing I/O operations.
Synchronization and Concurrency	Concepts of synchronization, race conditions, critical section problem, semaphores, mutexes, and deadlock prevention.
Deadlocks	Conditions for deadlock, detection, prevention, and recovery methods.
Security and Protection	User authentication, access control, encryption, system protection techniques, and security policies.
Operating System Structures	System calls, kernel and user space, layers of OS, microkernels vs. monolithic kernels, and OS design.
Virtualization	Virtual machines, hypervisors, containerization, and the role of virtualization in modern OS design.
Networking and Distributed Systems	Networking basics, OS role in networking, distributed OS, and inter-process communication.
Real-Time Operating Systems	Characteristics of real-time systems, scheduling, and managing tasks with strict timing constraints.
Case Studies of Modern OS	Study of popular operating systems: Linux, Windows, macOS. Understanding their architecture, components, and differences.
Operating System Security	Techniques for securing an OS: user authentication, encryption, firewalls, and managing system vulnerabilities.
